Abstract
A facility for producing reduced iron includes: a granulation apparatus that granulates raw material fine powder that contains iron and has a median diameter of 50 μm or less into granular powder in a fluidized bed formed by fluidizing medium particles that do not thermally decompose during fluidization; and a reduction apparatus that reduces at least the granular powder in the fluidized bed formed by fluidizing the granular powder.
